While his Holiness is more or less meh when it comes to non-consensual sex between a man and a boy, same-sex marriage just ain't cool in his book. So stop, says Pope Benedict.
The union of love, based on matrimony between a man and a woman, which makes up the family, represents a good for all society that can not be substituted by, confused with, or compared to other types of unions...[families should be] founded on matrimony between a man and a woman, to be the natural cradle of human life.
It should be noted that the Roman Catholic Church "teaches that homosexuality is not sinful but homosexual acts are." Hence Queer Eye, et al.
